The benching of the backcourt starters early in the second half of the Western Illinois contest gave us a preview of the rotation as we'll be seeing it later in the year.
Eventually, I predict the starters to be:

Mario Chalmers
Brandon Rush
Micah Downs
CJ Giles
Sasha Kaun

Defensive intensity and pressure are important, but KU needs offense. Candidly, the current starters aren't getting it done on either end. I don't think these five will start against St. Joes, but I expect these five to see significant minutes together on the court. The starting lineup should change within a game or two after that, and certainly before conference play.

Julian Wright and Darnell Jackson will rotate in to the frontcourt, with Moody playing only a defensive role (i.e. deep foul trouble or specific defensive assignment).

Rodrick Stewart and Russell Robinson will rotate in to the backcourt, with Jeff Hawkins playing only a defensive role (i.e. deep foul trouble or specific defensive assignment).
